Hey All.

Im looking at upgrading my Standard Evo 8 turbo soon.

I have been looking at upgrading to a GT3076R with a 44mm External wasgate and a .82 Rear housing.

My only issue, is that I dont want a lagg monster. I want the turbo to perform better then my existing turbo, but I dont want lagg for the sake of a big dyno number.

I DO NOT want to have full boost any later then 4000~4200rpm on 98 RON pump fuel.

Im not really looking for any more then 330 ~ 350whp. (It is VERY hard to make these numbers in australia on a stock turbo).

The car will be running on stock block and stock heads with some upgraded cams.

I have a set of HKS 264's that I was thinking about dropping in, but I have been recently been thinking about some revolvers.

I am looking for spool & torque over big power numbers. The car is used for daily driving & the occasional trackday. Im not really into drag's.

Regards,
Alex

Spool and drivability is VERY important to me

 

.82 a/r is going to lag on a 30r.

How much boost do you plan on running?

HKS 264's are a little weak for the setup you plan on running.

 

for that power level, get the 2871R or 3071R

 

why not a FP Red ? its basically the answer to all your requests.

 

Ill probebly be running 20 ~ 22 PSI...

Also, We find it a little more difficult to get the numbers that you do over here for some reason.

Will a GT3076R with a 0.63 turbine housing give me the boost responce that I want?

Also, As I said, in not really looking for the final figure. I want ALOT of torque. And a brutal midrange.

Alex

 

Cost. WAY to expensive to get here...

So garrett it is..

 

If you want torque and that power level I would buy a used FP Green from somebody here and have it shipped. That's not too expensive.

The HKS 264's are the best choice if you want to keep your peak torque in the low RPMs and stay in the 350 whp range. What type of dynos are you running on?

 

.82 a/r is not laggy at all. Look into the gsc s1 if you want to use the stock valvetrain.

 

Remember guys, Im just looking at a 'normal' GT3076R, not twin scroll or anything...

What sort of boost response should I get with the 0.82 housing..?

You think the HKS cams will assist in spoolup? Cause Thats all they will be there for.. In the hope i can reduce spool up times...

 

If all you want is 350 WHP with the capability to attain full boost by 4000 RPM, then I don´t think that the 3076R/.82 is the best way to do it. The 3076 is just not the best pump gas choice.

It´s a relatively slow spooler as well. The spoolup won´t be that much better than an HTA 35 and nowhere near the power potential. If you must have Garrett then buy the HTA compressor wheel from Forced Performance and get a 35.

The FP Red is the best bolton turbo. But, you say that you can´t afford the shipping. Then just pickup a used IX turbo there in your country. With the IX turbo you should be able to get to 350 easily. This spools a lot quicker than the 3076R/.82.

As far as cams are concerned, the Revolvers have been discontinued. The HKS 264´s are extremely mild. The GSC S1´s would be a better choice. At any rate, the Revolver 264´s and the HKS 264´s are not really comparable. Don´t be fooled by the fact that the advertised duration is the same.

 

A Standard evo IX turbo will not crack 350whp over here. We only have ONE evo green turbo'd car over 350whp. All the other 20G turbos are around the 330 ~ 340whp mark.

Im not going to limit myself to 330 ~ 350whp, but I also want some room to move if I ever decide I require more power.

I have bolted on EVERYTHING I can (minus cams, intake mani, exhaust mani & cooler) and I only have 260 ~ 270whp @ 22psi.

I am making full boost @ about 3800 rpm as it is so I dont want it too much laggyer then that.

 

In comparison to the 3076, the FP Red is a superior turbo in all respects. The compressor moves more air, it spools way quicker( some have reported 30+ PSI by 4000 RPM), it bolts right up to the factory manifold and a stock flanged DP. The Red is better on pumpgas. The Red has run mid-9 second quarter mile passes at over 145 MPH on a stock weight Evo. So, what is not to like about it?

 

Whats not to like about it? Cost!

Too expensive to get it here. Its almost AUD $4,000. Not worth it in my eyes. Also, its VERY unproven in australia. The evo green turbos dont even seem that impressive here... =(

Also, Im not running alky, race fuel or anything of the sorts.

We have a evo IX here running a Trust T67 kit, with full exhaust, AMS cooler, Trust piping, so basically all of the boltons (stock cams) and it is only running 300whp @ 24psi. WTF?!

Not to mention, drags dont mean anything to me, as Im not interested in a 1/4 mile. My car is a circuit car.

I guess that your perspective is different than mine.... obviously. several of the Time Attack cars here in the U.S, are switching over from the green to the Red. In some cases they have reported a half second lap time difference with just a preliminary tune. One guy stated that fully modded stock Brembos were not goung to hold up to the increased corner approach speeds possible with the Red.

The Drag speeds were just a reference point. 145 MPH+ in the quarter is seriously moving. This is the best turbo available for your car... period! This thing spools and the 3076 doesn´t. I like it at any price for the type of driving that you are describing. Garrett doesn´t produce a turbo that fills the same niche.

I live outside the U.S. myself and a shipped Red once it goes through our customs and shipping ends up costing me about $ 3700! I still think that it´s a bargain.

 

What do you guys use for gas? Salt Water? Real low, low numbers out there
